Objective To study the relationships among postpartum depression,dysfunctional attitudes and automatic thoughts.Methods 274 cases of postpartum women were estimated at fifth or sixth week after delivery by Edinburgh Postnatal Depression Scale (EPDS),Dysfunctional Attitudes Scales (DAS),Automatic Thoughts Questionnaire(ATQ) and some other forms designed by ourselves.Results ①The prevalence of postpartum depression was 18.20％.②The impact of culture degree on postpartum depression was statistically significant(x2 =12.37,P ＜ 0.05).③Compared with normal subjects,the postpartum depression group had significantly higher total score of ATQ (48.98 ± 12.35 vs 79.29 ± 23.90),total scores of DAS (118.92 ± 20.03 vs 148.03 ± 28.47),attraction or repulsion (13.82 ± 4.33 vs 18.01 ± 6.38),perfection (14.53 ± 5.91 vs 19.21 ± 5.23),compulsion(13.09 ± 3.61 vs 19.36 ± 4.98),seeking applause (14.97 ± 4.06 vs 18.78 ± 5.59),dependence (14.30 ±4.12 vs 19.23 ± 5.43),autonomous attitude(16.54 ± 3.67 vs 21.51 ± 4.81),cognition philosophy (12.32 ± 3.79 vs 18.16 ± 3.43),the difference was all statistically significant (P ＜ 0.01).④There was a significant positive correlation in postpartum depression and total scores of ATQ,total scores of DAS,attraction or repulsion,perfection,compulsion,seeking applause,dependence,cognition philosophy (the Pearson correlation was respectively:0.658,0.432,0.187,0.432,0.481,0.304,0.458,0.459,P ＜ 0.01).⑤Through stepwise regression analysis,automatic thoughts,cognition philosophy,compulsion,perfection and dysfunctional attitudes might play considerable role to predict the occurrence of postpartum depression.Conclusion Automatic thoughts,dysfunctional attitudes can predict postpartum depression to some extent.

Objective: To study left ventricular diastolic function (LVDF) in patients with coronary artery disease(CAD) by tissue Doppler imaging (TDI) and color Doppler echocardiography. Methods: The maximum velocity ( V max ) and time velocity integration(TVI) in early and late diastolic stage of mitral valve orifice of 80 patients with CAD and 79 normal subjects were measured by color Doppler echocardiography at apical 4 chamber view. Meanwhile, the V max and/or TVI of the myocardial motion spectrum of left ventricular lateral wall near the mitral valve annulet were measured by TDI. These data were compared and analysed by statistical method. Results: In the normal subjects, the older the subject, the lower the V max and TVI of early diastolic stage, the higher the V max and TVI of late diastolic stage. In CAD group, changes were not associated with ages and were affected by the degree of the myocardial pathology. The LVDF couldn't be exactly judged by color Doppler echocardiography when pseudonormalization blood flow spectrum appeared, but TDI technique was relatively sensitive. Any regional myocardial motion could be measured by TDI according to the examiner's design. Conclusion: LVDF by color Doppler echocardiography is simple and convenient. TDI technique can be used for determining overall LVDF and left ventricular systolic function. [

Objective:To screen the differentially expressed genes on whole expression profiles of the inflammation-related cytokines in mice infected with influenza virus by the gene chip technology, and to explore the intervention effect of Shufeng Xuanfei Jiedu formula.Methods:Male ICR mice were divided into normal group (N group), influenza virus infective model group (M group), Oseltamivir control group (C group) and Shufeng Xuanfei Jiedu formula high, medium and low dose groups (SH, SM, SL groups) according to the random number table method, with 10 rats in each group. A mouse model of influenza virus pneumonia was reproduced by nasal drip of influenza virus strain FM1 (0.05 mL). In N group, 0.05 mL normal saline was used. In SH, SM and SL groups, Shufeng Xuanfei Jiedu formula was used 2 hours after intranasal infection (2 times, equal and 1/2 of the clinical treatment dose, approximately 3.8, 1.9 and 1.0 g·mL -1·d -1) for 4 days. In C group, the dosage of Oseltamivir was 2.5 g·mL -1·d -1. In N group and M group, distilled water was given (0.2 mL once a day). On the 5th day, the whole lung of mice was taken. The lung index was calculated, and the pathological sections were observed. The total RNA of lung tissue was extracted and detected after hybridization with mice whole gene expression spectrum chip to select differentially expressed genes of chemokine pathways. The expression intensity ratio of the chip probe signal in each group vs. M group was calculated, and P < 0.05 and log 2ratio > 1 were up-regulated genes, while P < 0.05 and log 2ratio < -1 were down-regulated genes. Results:Compared with the N group, the lung index in the M group was significantly higher, and pathological changes were found in lung tissue, which suggested that the model of influenza virus infection was successfully established. Compared with the M group, the lung index of mice in C, SH, SM, SL groups was significantly lower (0.96±0.14, 1.45±0.22, 1.14±0.18, 1.22±0.21 vs. 1.72±0.15, all P < 0.05), and the extent and degree of lesions were reduced, however, there was no significant difference among the groups. Gene chip analysis showed that there were more differentially expressed genes in N group vs. M group, SH group vs. M group, SM group vs. M group, SL group vs. M group. It could be used for further signal transduction pathway screening. Compared with N group, the differential gene expression of chemokine C-C ligands (CCL-3, CCL-5) and chemokine C-X-C ligands (CXCL-9, CXCL-10) in M group were significantly up-regulated [log 2 (M group/N group) were 6.64, 3.51, 5.40, 6.64, respectively]. Compared with M group, the gene expressions of CCL-3, CCL-5, CXCL-9 and CXCL-10 were significantly down-regulated in C, SH, SM and SL groups [log 2 (C group/M group) were -3.96, -2.26, -3.12, -2.40; log 2 (SH group/M group) were -5.57, -2.37, -1.57, -1.01; log 2 (SM group/M group) were -4.35, -1.47, -1.26, -1.74; log 2 (SL group/M group) were -2.86, -1.86, -1.23, -1.39, respectively]. Conclusion:Shufeng Xuanfei Jiedu formula inhibits inflammatory damage in mice after influenza virus infection by down-regulating the expressions of CCL-3, CCL-5, CXCL-9 and CXCL-10 on chemokine pathways.

Objective:To investigate the discomfort of chest wall approach area in patients undergoing endoscopic thyroidectomy by a gasless unilateral axillary approach (GUA), and to analyze its influencing factors. To provide a basis for the development of targeted improvement measures.Methods:A total of 153 patients with GUA from May. 2023 to Aug. 2023 in the Department of Thyroid Surgery, the First Affiliated Hospital of Zhengzhou University were selected as the study subjects. The general information questionnaire was collected one day before operation, the pain scales were assessed one day and three days after operation, and the pain and numbness scales were assessed one month after operation. The t test or χ2 test was used for comparison of baseline data between groups according to different types of variables. The patients were divided into two groups: less than moderate pain group (two postoperative average VAS scores<4) and more than moderate pain group (two postoperative average VAS scores ≥4). Mild numbness group (postoperative VAS score<4) ; Moderate and severe numbness group (postoperative VAS score ≥4). Multivariate binary Logistic regression was performed with pain discomfort and numbness discomfort as dependent variables to find possible influencing factors. Results:A total of 153 valid questionnaires were collected. There were 125 patients in the moderate pain group; There were 28 patients in the moderate and above pain group. There were 94 patients in the mild numbness group. There were 59 patients in the moderate to severe numbness group. Multivariate binary Logistic regression results showed that, exercise habits ( OR=0.07 95% CI=0.006, 0.409), operation duration ( OR=1.026 95% CI=1.001, 1.054), total drainage volume ( OR=1.122 95% CI=1.07, P<0.05), 1.198), and drainage tube indwelling time ( OR=0.012 95% CI=0.0, 0.187) had an impact on the discomfort of the chest wall approach area, and the difference was statistically significant ( P<0.05). Gender, BMI, marital status, education, occupation, handed-side surgery, handed-side axillary surgery, smokess and alcohol history, intraoperative blood loss, and length of hospital stay had no effect on the discomfort of chest wall approach area, and the difference was not statistically significant ( P>0.05) . Conclusion:Exercise habits, operation duration, total drainage volume, and drainage duration are independent predictors of discomfort in GUA patients.

【Objective】 To understand the current status of medical staff’s awareness of hospital infection prevention and control during the epidemic of COVID-19 in Shaanxi Province and analyze its influencing factors. 【Methods】 The questionnaire was designed on the "Questionnaire Star" website. Based on the WeChat platform, a voluntary sampling method was used to invite online questionnaires. From March 13 to 29, we collected a total of 8037 questionnaires, 30 of which did not meet the requirements and had logical problems, and finally 8 007 valid questionnaires were obtained. 【Results】 A total of 8 007 medical staff were surveyed. Among them, Medical staff of Grade 3A, Grade 3B, Grade 2A, and Grade 2B hospital accounted for 39.6%, 2.3%, 55.3%, and 2.6%, respectively. The average age of the respondents was (32.1±7.2) years old, including 7 199 nurses and 501 doctors. The training effect was statistically significant in different regions, different hospital levels, whether it was a designated hospital and whether there were sensor control supervisors, as well as medical staff of different specialty, professional title, and work area (all P<0.01). The basic cognitive situation of the surveyed subjects showed that most medical staff in Shaanxi Province had a correct rate of less than 30% in whether they needed to disinfect before de-protection and how to disinfect the hospital environment. Multivariate linear regression analysis showed that the cognition level of medical staff in Grade A hospitals was significantly lower than that in Grade A hospitals (P<0.01). The cognition level of medical staff in designated hospitals was significantly higher than that of others (P<0.01). The cognition level of medical staff in hospitals with sensory control supervisors was significantly higher than that of others (P<0.01). The cognition level of people aged 25-34 and 35-44 was significantly lower than those aged 45 and above (all P<0.01). The cognition level of medical technicians and service personnel was significantly lower than that of doctors (P=0.02 and <0.01, respectively). The cognition level of medical staff with intermediate, associate senior, and senior professional titles was significantly higher than the cognition level of those with junior and below professional titles (all P<0.01). The cognition level of medical staff in fever clinics, emergency departments, isolation wards, ICU and other surgeries was significantly higher than that of those working in ordinary outpatient department (P=0.01, 0.03, <0.01, 0.02, and <0.01 respectively). 【Conclusion】 Most medical staff in Shaanxi Province have misunderstandings about whether they need to disinfect before de-protection and how to disinfect the hospital environment. Moreover, we found that the awareness of medical staff in Shaanxi Province of hospital infection prevention and control during the epidemic of COVID-19 was affected by the hospital’s level, whether it was a designated hospital, whether there were sensor control supervisors, as well as the age, specialty, professional title and work area of the medical staff.
